Analysis of the factors influencing the college students’ employment willingness under the strategy of “strengthening the provincial capital”

University graduates can inject strong impetus into the development of cities. However, China’s “Strengthening the Provincial Capital” strategy attracts many college graduates, resulting in many limitations in attracting college students to employment in non-provincial capital cities. This paper systematically studies college students’ work and entrepreneurial intention factors. We conduct a social survey of employment and entrepreneurial intentions among university graduates in Xiangtan City, Hunan Province, and obtain 12,897 questionnaires. Then, we construct an index analysis system (IAS) and analyze the 12897 questionnaires systematically based on IAS. The results show that urban characteristics and personal orientation most directly affect college graduates’ employment and entrepreneurial willingness. Based on the statistical conclusions, we put forward corresponding policy recommendations. Colleges should build a “government-enterprise-school” cooperation mechanism, implement strategically focused attraction policies following local conditions and local conditions, and promote the employment of college students to promote employment and entrepreneurship in non-provincial capitals.


Introduction
Many provinces in China are currently developing a "Strengthening the Provincial Capital" (SPC) strategy. SPC is the policy to rapidly concentrate the resources in the provincial capital cities and promote high-end human resources gathering through the "war for talents" to strengthen the provincial capital cities. SPC is conducive to promoting the development of the provincial economy and raising the development ranking of provincial capital cities. Unfortunately, the excessive "resource siphon effect" also leads to a high proportion of the provincial capital city's economy, resulting in a significant gap in urban development. SPC is not conducive to the balanced distribution of college students to different cities for employment. SPC has caused great trouble for non-provincial capital cities to attract and retain talents and increased the imbalance and limited distribution of talent resources. Employment is the foundation of people's livelihood. Promoting the multi-channel employment and entrepreneurship of college students is society's focus. However, in most countries, graduates have faced the problem of insufficient employment opportunities [1,2]. There are sometimes opportunities, but they are challenging to retain [3]. China has increased support for college graduates in employment and entrepreneurship to stabilize employment and promote entrepreneurship. On the one hand, colleges continue to promote postgraduate promotion, postgraduate recruitment, and college recruitment. On the other hand, based on improving the quality and level of their innovation and entrepreneurship education, they are strengthening their reforms to promote the further development of higher education. However, under the strategy of "strengthening the provincial capital," the supply and demand structure of college students is unbalanced, the professional setting structure of colleges and universities is not optimized enough, and the degree of matching with the market is low [4]. The proposed employment guidance is out of the needs of students [5]. In addition, since the 21st century, the popularization of higher education in China has led to a large-scale increase in the supply of college students [6]. Under the combined effect of multiple pressures, such as the transformation of the domestic economic and industrial structure and the continuous and repeated global new crown epidemic, the employment problem of college students has become increasingly prominent. There are still many phenomena, such as "difficulty in employment" and "slow employment" in the employment of college students. The key to promoting the employment of college students is to take the needs of college students as the starting point. Therefore, understanding the influencing factors that affect the employment of college students and exploring the effect of these factors is the key to promoting the effect of these factors are the key to promoting the employment and entrepreneurship of college students.

Literature review
Recently, academia has carried out many explorations about the employment intention of college students. Overall, the employment intention of college students is affected by multiple factors, including economic, social, college, family influences, and individual levels. However, at present, there are more theoretical studies on college students' employment intentions, and fewer studies through the indicator system [7].
Many researchers have studied the factors that affect the employment of college students from a single dimension. Holland's Theory of Career Choice points out that personality traits affect work behavior and play a significant role in career choices. Holland's Theory of Career Choice points out that personality traits affect work behavior and play a significant role in career choices. Holland suggests that professional characteristics should be reasonably matched with personality traits because this can promote employees' enthusiasm for work [8]. P.A. Baffour et al. took 302 fourth-year medical college students in Ghana as the research object and found that occupational motivation factors had no effect on the willingness of college students to obtain employment in rural areas, while the educational status of parents hindered the willingness of college students to obtain employment in rural areas [9]. College graduate identity theory proposes that the result of the joint effect of college graduates' selfidentification and employers' mutual identity is to achieve employment. If graduates want to be really hired, they must be recognized by the employer and believe that they have the ability to be competent for the post [10]. Gershuny proposed that internal subjective factors such as self-esteem, self-confidence, motivation, active participation and interest have a significant impact on the employment quality of college students [11]. Other single-dimensional influencing factors, such as family education and career orientations on subjective, can significantly impact employment choices [12]. Social capital has an important impact on the job search process of college students [13,14]. In particular, the occupational status of parents (especially the occupational status of fathers) and their education levels can significantly affect their children's access to jobs [15][16][17]. Under the framework of econometrics, J.Y. Xu found that the relationship between employment and major is a factor closely related to whether graduates have a positive career [18]. W.S.M. Boysen et al. believe that entrepreneurship education for college students has obviously achieved the transformation of higher education, and improved the employment willingness and quality of college students [19]. Influenced by gender, girls have greater influence on employment choices [20][21][22]. Cudeville and Gurbuzer use Turkey as a research object and find that there is a gender bias in the labor market between male and female practitioners [23]. On the other hand, the researchers also analyzed the push-pull effect of external environmental factors on college students' rural employment intention. As proposed by A. Amalba et al., the level of community education and service (COBES) will significantly improve the willingness of Ghana medical students to be employed in rural areas [24].
Other researchers have begun to study the influencing factors of college students' willingness to obtain employment from a multi-dimensional perspective. Dominitz and Manski conduct a collaborative study on the income expectation of 110 high school students and college students in Wisconsin. They conclude that income expectation has an essential impact on employment. The level of income expectation is affected by gender, family background, school, major, grade, grades, sources of job search information, and other factors [25]. Maarja Beerkens found that work during school has almost no negative impact on learning, and student employment has become a reflection of students' ability. Compared with poor learning of students, students who study well are more likely to find good jobs, higher education, teaching quality standards and the perceptions of students and employers all affect student employment [26]. Paul and Murdoch studied the employment situation of French college students and believed that the education level of college students, the type of school and the social background of college students have an important impact on the employment intention of college students [27]. The higher the education level, the more conducive to finding a suitable job [28]. Kivinen et al. point out that the region's unique natural and economic characteristics will directly impact the employment choice of college students [29]. E.J. Parsons et al. assessed the relationship and relative importance of some factors affecting women's career expectations and concluded that attitudinal factors best reflect career expectations [30]. Women with higher career expectations are satisfied with their lives, have confidence in career planning, and are willing to delay marriage [31].
In addition, entrepreneurship is an important form of employment, entrepreneurial intent is a necessary condition for understanding the entrepreneurial process [1]. Therefore, scholars have also conducted in-depth research on entrepreneurial intentions. There are many factors that affect college students' entrepreneurial willingness, which can be summarized as personal characteristics, family background, education, entrepreneurship, gender entrepreneurial environment, etc. [32,33]. J.E. Douglas et al. proposed that entrepreneurial intention is affected by individual factors such as individual entrepreneurial attitude, self-efficacy, entrepreneurial ability, personality traits, and individual entrepreneurial experience. Strong support from relatives and friends will enhance entrepreneurial willingness [34]. The more positive the individual entrepreneurial attitude, the stronger the entrepreneurial intention [35]. At the same time, Some factors, such as entrepreneurial orientation, entrepreneurship education, and university support, have a significant positive impact on the entrepreneurial intention of fresh graduates [36]. Good entrepreneurship education can cultivate students' essential entrepreneurial ability and quality, significantly improve the employment quality of college students, and enhance their willingness to employment [37]. At the same time, good entrepreneurship education can also improve entrepreneurial passion, which in turn positively affects entrepreneurial intention [38]. In addition, social environments such as legal regulations and government support are also key factors affecting individual entrepreneurship [39], which both support and hinder entrepreneurship [40]. The analysis of the influencing factors of employment intention is the key to correctly guiding the high-quality employment of college students. However, from the above, it can be seen that scholars have analyzed the influence of employment intention a lot. However, on the whole, they are scattered and not systematic enough and lack a unified analysis system. Moreover, the existing research on the employment and entrepreneurial willingness of college graduates in non-provincial capital cities is insufficient.
Different from the current researches, this paper, based on the questionnaire data of 12,897 college students in Xiangtan City, Hunan Province, from the four dimensions of the region, university, family, and individual, the factors of college students' employment and entrepreneurship willingness non-provincial capital cities are analyzed. Furthermore, use the established college students' employment and entrepreneurship willingness index system to analyze the data systematically. Rank the effects of influencing factors, and formulate practical and feasible policies and measures from macro-strategic planning to a specific implementation to promote the rational allocation of human resources between cities and promote the attraction of non-provincial capital cities to college students. Promote the employment of college students.

Background of Xiangtan City
As a typical non-provincial capital city in the central region, Xiangtan City has a severely aging population. Various talent pro jects vigorously promoted by surrounding provinces and provincial capital cities continue to attract the inflow of college students. SPC has intensified the fierce competition for talents between regions, and the gradual disappearance of the demographic dividend has brought specific challenges to Xiangtan City.

Research design
In this paper, we conducted extensive research on the employment of college students. Specifically, we use literature surveys, interviews, stratified sampling, questionnaires, and other methods to collect many multi-dimensional factors affecting college students' employment. Furthermore, we deeply analyze the data using the analytic hierarchy process, factor analysis, and cluster analysis.
We divide the process of questionnaire design and investigation into three stages. First, we selected about 30 respondents to conduct an open-ended questionnaire survey to discover measurement indicators and prepare for the formulation of a formal questionnaire. Then, we selected about 175 respondents according to the sampling plan. Then, the first draft of the questionnaire was carried out and tested, and revised the content questionnaire through the project analysis to improve the quality of the questionnaire. Finally, we adopt the stratified sampling method to conduct a formal survey and sample the whole sample.
After obtaining the survey data, we consider a preliminary analysis of the full effect of the survey questionnaire, explore the effectiveness of each question set, and use SPSS 22.0 for statistical analysis of the pre-investigation data. Since it is a pre-investigation, it can be divided into four levels: basic information, employment expectations, employment cognition, and entrepreneurial cognition. It is necessary to make specific tests for the problems at each level to improve. First, we conduct the project analysis deleting the defective items according to the results. Second, we conduct the exploratory factor analysis, in which we delete some defective items according to the factor load value. After that, we conduct the questionnaire's construction reliability and validity analysis. Finally, after the items were reduced, an internal consistency reliability analysis was carried out on the questionnaires. The specific methods are as follows: 1. Project analysis. The correlation-coefficient method is used to test the total correlation degree of the items. It is the degree of consistency between each item and the questionnaire. For the correlation method, the Pearson product-difference correlation is used in this paper, and the analysis results can be obtained according to its analysis statistics. According to the statistical results, the items and basic information of employment cognition have a high degree of consistency with the items and basic information of employment expectations. In the entrepreneurial intention and basic information, the correlation coefficient of the 18th question is 0.03, and the correlation coefficient of the 21st question is 0.102, so these two questions are deleted, and the rest are above 0.20, which meets the requirements. For the T-test method, this paper uses the independent sample high-low grouping T-test to calculate the discrimination of the items. Through the independent sample T-test, the CR value of a total of 3 items in the questionnaire was less than 3, which did not reach the significant level, which indicated that these items had no discrimination and needed to be deleted. They are two questions in employment expectations and 1 question in employment cognition.
2. Exploratory factor analysis. According to the item analysis results, this paper deletes the poor items in the questionnaire, and the remaining items enter into a factor analysis. There are two purposes of factor analysis, one is to further screen the items according to the factor load value, and the other is to exploratively verify the factor structure of the questionnaire, which is constructed validity. Construct validity refers to the degree of correlation between items and the concepts they reflect, and it can explore its construct validity using factor analysis. Before doing factor analysis, KMO and Bartlett's sphericity test are usually performed. As shown in Table 1, the table provides the KMO value and Bartlett's sphericity test value of each part of the questionnaire before factor analysis. The results show that this questionnaire is suitable for factor analysis.
For factor analysis, we first use principal component analysis to extract factors. Then, we use variance maximum orthogonal rotation (Varimax) to rotate the axis. Finally, we limit the number of factors of each scale based on the gravel diagram (Scree Plot) and the dimension defined by the concept. We further screened the items according to the analysis results and obtained the factor analysis results shown in Tables 1 and 2. Based on the results, we delete the items whose load value is less than 0.3 and those greater than 0.3 but cannot reflect the aggregated dimension content.
After deleting the above items, this questionnaire's factor loading value (judging aggregate validity) has reached a relatively ideal level. In addition, factor analysis also provides the Percent of Variance of each dimension. This value The closer it is to 1, the higher the degree to which the dimension explains the concept. In the development of the questionnaire, the Cumulative Percent of Variance is usually required to reach more than 50%, and for a developing questionnaire, more than 30% is also acceptable. After inspection, the explained variance of this questionnaire scale is above 50%, which is an ideal level. 3. Reliability and validity analysis. For the reliability analysis of the questionnaire, the internal consistency Alpha coefficient method is generally used. The higher the coefficient, the more consistent the content of the test. After inspection, the Alpha coefficients of this questionnaire are all above 0.8, as shown in Table 3. After factor analysis, this paper deletes five items. In addition to the three deleted items in the previous item analysis, eight items were deleted, and the questionnaire items were reduced from 35 to 27.
This paper examines the validity of the scale from two aspects: content validity and constructs validity. The dimensions and items of the questionnaire are derived from literature research, preliminary interviews, open-ended questionnaires, and classic scales. Experts in educational management, educational statistics, teaching evaluation, etc., are invited to review and revise before and after the pre-investigation of the questionnaire. Ensure that the items and dimensions of the questionnaire reflect the content that college students should include in their employment and entrepreneurship and make them representative. The measure of construct validity can be obtained by factor analysis, which is to find out the common factors that affect the test by performing factor analysis on a group of tests. A load of each test on common factors (the correlation between the test and each factor) is the factor validity of the test, and the proportion of the total variance of the test scores from related factors is an indicator of the test's structural validity. Exploratory factor analysis showed that the structure of the questionnaire was reasonable, which ensured the construct validity of the questionnaire.
When pre-testing the later interview questions, the research group selected two relevant persons from the four groups of local enterprises, colleges and universities, government, and entrepreneurs through the teacher relationship, totaling eight people. They will send the questions set for this part of the group to the other party in the form of an online chat and let the other party answer. After receiving the answer sheet, they will analyze the responses of the two people in each group. If two more people cannot answer a particular question, we then delete the question. If the level of a question answered by both of them is low, the question set will be more precise. If two people's answers to a question are massively different, the answers will be considered according to the actual situation. Furthermore, modify the question settings

College students' employment willingness under the strategy of "strengthening the provincial capital" answered by two people to a certain extent to ensure that the situation answered by each person can represent the final situation of this type of sample. After completing the pre-test work and repeated deliberation, determine the final interview content.

Survey data
This paper conducts a survey on the employment and entrepreneurial intention of students from 10 colleges and universities in Xiangtan City and uses the method of random sampling to obtain data. The specific survey subjects include fresh undergraduates, graduates within two years of graduation, high-level talents, and shortage of talents. The graduation period is relaxed to less than five years of graduation. This paper finally collected 12,897 valid and complete questionnaires. In order to ensure authenticity and effectiveness, we exclude the college students who chose the destination of their studies in the questionnaire. Finally, 8393 questionnaires are preserved. 6,754 respondents are employed, and 1,639 were about starting a business. In addition, around the designed questions, adopt a structured form to interview the entrepreneurial people. Based on the effective information obtained from the questionnaire, the main consideration factors are obtained according to the pre-investigation design and the analysis of the results, and an indicator system for analyzing the employment intention of college students from four dimensions: region, family, individual and university is constructed. Then, based on the tomographic analysis method and cluster analysis method, we have divided and classified the influencing factors of employment and entrepreneurship according to their importance and relevance, and builds relevant models to conduct in-depth analysis of the collected data.
According to the questionnaire analysis, the proportion of males and females in the sample data is almost equal. Undergraduates, followed by junior colleges, dominate the academic background. The number of technical secondary schools is small; the subjects are mainly liberal arts, accounting for 40.29%, followed by science and engineering, and the distribution of the three ma jor subjects is balanced. This is in line with the situation of colleges and universities in Xiangtan City, so the basic situation of other personal statistics can reflect the general characteristics of college students in this city. The proportion of household registration in Xiangtan City is 12.74%, of which rural household registration accounts for 7.85% and urban household registration accounts for 4.89%. The proportion of household registration in other cities and states in the province is 54.27%, of which rural household registration accounts for 37.43%, and urban household registration accounts for 16.84%. The proportion of household registration in other provinces is 32.99%, including 21.68% in rural areas and 11.31% in cities and towns of other provinces. The proportion of non-only children among local college students is twice that of only children (69.14%). This situation is basically in line with the family status of students with rural household registration (66.96%).

Selection of analytical indicators
Regarding the indicators of employers, this paper selects the factors that affect the employment willingness of local college students, including welfare benefits, job demands, and requirements. The benefits are mainly reflected in the salary level, and this indicator is included in the personal dimension. The consideration of job demand and indicators is divided into two aspects. First, college students will not consider the job demand and requirements of local enterprises in the early stage of their intention to choose the direction. Second, enterprises' job demands and requirements are more relevant to the later employment results. So it is not considered for the time being. The specific dimensions and indicators are described as follows.
4.1.1 Regional dimension. The region is an important indicator that affects college students' employment and entrepreneurship. The characteristics of occupational social structure depend on the strength of the city and the preference of college students' employment choices. This means that the particular policies and culture corresponding to each region will also affect its decision-making. The structure of regional dimension indicators is shown in Table 4.
The city's economic status, culture, and public services have an important impact on graduates' employment intentions. At the same time, the city's social values, living habits, and social fashions will also be taken into account. An employment policy is a guideline for allocating human resources for college students formulated by the state or local government. In order to realize the line and policy of a certain period, employment policy should meet the needs of social development in a particular stage and promote the full utilization and distribution of human resources. City preference is influenced by the economy, politics, culture, family, geography, etc. It is a kind of emotion and tendency to choose a city hidden in people's hearts.

Family dimension.
Families arise based on multiple relationships such as marriage, blood, or adoption. The family dimension referred to in this paper also includes the influence of close relatives and friends other than family. As the growth and life elements that college students rely on most closely and trust, they are closely related to employment. The structure of the dimension indicators is shown in Table 5.
The family economy includes the family's economic source and level. If the family has a particular background and relationship, they may directly nominate their children's employment choices. The parents' view on career choice shows the value trend of parents in their children's career choices. Parents' opinions can affect college students' choices, especially the choice of employment location. The employment concept of relatives and friends refers to the employment concept and employment trend of relatives, friends, and male and female friends.

Personal dimension.
College students as the primary selection subject, their factors are the most critical influencing factors, involving gender, major, education, salary requirements, etc. When choosing employment, college students pay attention to remuneration and their ability and quality and realize their ideals. The descriptive statistics section embodies the measurement and selection of basic personal information here, which mainly sets three aspects: employment outlook, personal ability, and quality, and salary and treatment requirements, as shown in Table 6.
Salary package reflects the degree of expectation of college students on the employer's salary. It includes the employer's welfare, fundamental security, promotion space, etc. It is closely related to the industry and place of employment that college students choose their employment.

PLOS ONE
College students' employment willingness under the strategy of "strengthening the provincial capital" Ability quality shows the relevant ability and quality displayed by an individual at work. Individuals need to choose employment methods according to their ability and quality. It is a reactive tendency of an individual to employment that reflects the individual's concept and attitude. The influence of individual employment intention under different employment views varies greatly.

University dimension.
Whether the professional setting of colleges and universities is reasonable, the quality of teaching, and whether the employment guidance plays an irreplaceable role in forming the quality of education, education level, and employment outlook that college students receive during their school days. Therefore, the university level has a farreaching effect on students' employment choices, and its index structure is shown in Table 7.
The setting of ma jors affects the quality and level of training in colleges and universities. Some colleges and universities have extensive and comprehensive professional settings, focusing on theory and away from social needs. Some professional settings meet social needs, but they are too scattered and have a narrow scope of employment, which will affect college students' employment willingness. Employment guidance can deliver timely entry information to potential employers in colleges and universities, build a bridge of communication between recruiting units and applicants and reduce the cost of obtaining information for college students in employment to avoid blind employment of college students. Teaching quality is the primary evaluation of education in colleges and universities. High-level schools will enjoy more financial appropriation, higher social reputation, sufficient teacher resources, and teaching equipment, resulting in higher teaching quality.

An analysis of the factors affecting college students' employment willingness
In this paper, when we analyze the influencing factors of college students' employment intention, we mainly conduct research on the relevant influencing factors of development intention in Xiangtan City, and sort out the effect of these influencing factors. At the same time, these influencing factors are classified and classified according to their importance and correlation, so we use AHP and cluster analysis to analyze. It is a simple method for making decisions on some more complex and vague problems, and it is especially suitable for those problems that are difficult to analyze fully quantitatively. In the systematic analysis of social, economic, and scientific management issues, scholars often face a complex system composed of many interrelated and mutually restricting factors, which often lack quantitative data. Analytic Hierarchy Process (AHP) provides a new, concise and practical modeling method for the decision- making and ranking such problems. Clustering is to divide a group of objects into clusters so that the similarity within the cluster is high and the similarity between the clusters is low. It mainly puts objects with the same or similar properties in the same set. Objects with different properties are placed in different collections. Cluster analysis is a crucial data mining technology widely used in various databases, including mathematics, computer science, statistics, biology, and economics. There are many influencing factors designed in this paper, the AHP and cluster analysis meets the research needs. 4.2.1 Model establishment and operation process. 1.The establishment of a hierarchical structure. The primary purpose of this study is to explore the impact of the four employment dimensions of regions, universities, individuals, and families on the employment choices of college students in Xiangtan City. According to the requirements of the model construction of the tomographic analysis method, the factors affecting the graduation and employment of college students in Xiangtan City are constructed into three layers. The first is the target layer, that is, employment and entrepreneurship. The second is the dimensional layer, including regional, family, personal, and university. The third layer is the index layer, which divides the four-dimensional into 12 sub-indicators. They together constitute the structural model of the factors affecting the employment intention of college students in Xiangtan City, as shown in Fig 1. 2. Judgment matrix. In order to compare the effects of the 12 significant factors on employment, we selected the factors for pairwise comparison and established a comparison matrix. According to the structural model established in Fig 1 above, we have established 5 paired judgment matrices: Tables 8-12.
In this paper, we use excel to average the results of the judgment matrix and then calculate the weight of the tomographic analysis method and judge whether the test results are consistent. This paper uses the method described below to deal with the judgment matrix of employment and entrepreneurial intention of college students in Xiangtan City.

3. Calculation of weights and consistency check of judgment matrix. There are 6,717 questionnaires related to employment in this study. We use excel to average the results of the judgment matrix to obtain an average judgment matrix, and then calculate the weight of the tomographic analysis method and whether the test results are consistent. The following four categories of influence dimensions in this paper take the calculation of the judgment matrix of Table 8. Judgment matrix of four dimensions affecting the employment of college Students in Xiangtan City.

University dimension (B3) Major setting (C7) Teaching quality (C8) Employment guidance (C9)

The simplified sum-product method is used to calculate the weight of each indicator. The first step is to uniformly normalize each column of the judgment matrix to obtain a new standard matrix. The sum of each column in the judgment matrix calculated by adding.
Then each element in the matrix is divided by the total number of corresponding columns, using the formula: Calculated: Indicates that the former is slightly more important than the latter 5 Indicates that the former is significantly more important than the latter 7 Indicates that the former is strongly more important than the latter 9 Indicates that the former is extremely important compared to the latter 2,4,6,8 reciprocal Represents the median value of the above adjacent judgments If the importance of factor i over factor j is a_ij, then factor j and factor i The ratio of importance is a ji = 1/a ij, and a ij>0, a ii = 1 https://doi.org/10.1371/journal.pone.0278164.t013

This paper calculates the weight of the influence of several sub-indicators by MATLAB and obtains the following results.
Regional. It is also ranked by weight: city strength (0.68) >employment policy (0.21) >city preference (0.11). It can be seen that among the regional factors, city strength is the key factor affecting college students' career choices in Xiangtan City, followed by employment policy and city preference.
Family. According to the order of weight: family economic status (0.53) >relatives and friends' view of career choice (0.31) >parents' view of career choice (0.16), it can be seen that among family factors, family economic status is the main factor, followed by relatives and friends view of career choice and parents' view of career choice.
Personal. It is also ranked by weight: professional setting (0.51) >teaching quality (0.28) >employment guidance (0.23). It can be seen that among the factors of colleges and universities, the main reason that affects the employment of college students in Xiangtan City is the professional setting, followed by the teaching quality and employment guidance.
University. It is also ranked by weight: salary and treatment (0.54) >personal ability and quality (0.34) >personal employment outlook (0.12). It can be seen that among personal factors, salary and treatment are the main factors, followed by personal ability and quality and personal employment outlook.
Comprehensive. In the dimension layer, the individual dimension (0.33) and the regional dimension (0.31) are the two most important dimensions affecting the employment of college graduates in X city, followed by the university dimension. (0.25), and again the family dimension (0.11). Remuneration (64\%) is the primary factor in the personal dimension, city strength (68\%) is the primary factor in the regional dimension, majors (51\%) in the university dimension is the primary factor, and family economic status (53\%) in the family dimension is the primary factor. In the indicator layer, from the perspective of total weight, salary and benefits (0.2112) \textgreater urban strength (0.2108) \textgreater professional setting (0.1275) \textgreater personal ability and quality (0.0924) \textgreater teaching quality (0.07) \textgreater employment policy (0.0651) \textgreater family economic status (0.0583) \textgreater employment guidance (0.0575) \textgreater city preference (0.0341) = relatives and friends view on career choice (0.0341) \textgreater personal employment view (0.0264) \textgreater parents view on career choice (0.0176).

Application and analysis of cluster analysis 4.3.1 Model establishment and operation process.
In applying the cluster analysis method, this paper analyzes the 30-question indicators through the deviation averaging method (Ward method) and case (Q-type) systematic clustering according to the question set and targeted indicators of the employment willingness questionnaire. Then, the squared deviation sum of the two elements added after merging the two elements is used as the distance of the classification, as follows.
In the formula: D 2 pq is the inter-class distance of cluster analysis; W t , W p , W q are the sum of squared deviations of samples in the r, p, and q classes, respectively.

Model solution results and analysis.
After using SPSS 20.0 software to calculate the data, the cluster analysis pedigree diagram (Fig 2) was obtained. From this, it can be concluded that when the class spacing = 14, the 30 categories of employment intentions can be divided into four categories.
The first category aggregates 20 willing options, namely 1, 2, 3,4,5,7,8,9,11,12,13,14,15,16,17,18,21,22,23, and 25, the second category gathers 10 and 19, the third category gathers 27 and 29, and the fourth category gathers 6, 20, 30, 24, 26 and 28. The focus is on the fourth category, whether to stay in Xiangtan City for employment. In the clustering situation of the degree of willingness, this option is 30 questions. This category also aggregates the housing price level of the employment place, the urban development space of the employment place, and the situation of the work unit. From this point of view, college students will comprehensively consider job selection, the development space of the city, and the cost of settlement when considering employment in Xiangtan City, and finally determine whether they are in Xiangtan City. main factors of development.

Analysis of the influencing factors of college students' entrepreneurial intention

Conclusion
This paper systematically analyzes the influencing factors of college students' employment and entrepreneurial intention. The influencing factors of college students' employment intention are diversified, and the effect of each factor is different. Among them, the personal and regional dimensions are the most critical, followed by the university and family dimensions. Other factors, such as salary, urban strength, family economic status, etc., play a relatively weak role. In addition, it also gathers the housing price level of the employment place, the urban development space of the employment place, and the situation of the working unit. From this point of view, college students pay more attention to the salary package of employment, the development space and strength of the city, and their professional counterparts, which are greatly affected by personal factors. Therefore, in the process of promoting the employment of college students, we can further expand the employment path of college students by giving full play to the organization and coordination role of the government, adjusting the employment concept of college students, improving the attractiveness of nonprovincial capital cities, and rationally setting majors.

Policy recommendations
Promoting employment-oriented reform of talent education in colleges and universities. Colleges should offer career development and employment guidance, career planning, etc., courses to help college students improve their employability. Reasonably guide college students to establish realistic employment expectations, design reasonable career-planning plans, and shorten the employment adaptation period. Building a "goverment-enterprice-school" cooperation mechanism. Under the full play of the organization and coordination role of the government, a particular cooperative management agency jointly formed by the departments of education, economy, finance, taxation, labor, etc. was established, and various functions and powers were assigned to the management agency. The government-enterprise-school cooperation platform was established as a whole.
Implementing a strategy-focused attraction policy based on local and regional characteristics. For example, it can implement more proactive fiscal policies to make up for the shortcoming, such as low housing prices, low consumption, and characteristic industries in Xiangtan City, which is also Longboard.
Strengthening the sensitivity of the university market. We will strengthen the supply-side reform of higher education and treat the social needs as guidance, thus cultivating high-quality talents that meet social needs [41,42]. Colleges should set up majors that match the market as much as possible and make corresponding adjustments to majors that are unpopular and less socially needed, including the number of students enrolled, teaching process and teaching methods, etc., and try to avoid unemployed students before graduation.
The government should give sufficient policy guidance to fully and effectively play its role. The government should deepen the reform of the personnel system and improve social security. At the same time, the government should provide more preferential policies, optimize the distribution structure of human resources, promote the employment of college students at the grassroots level, and advocate self-employment.
